About this study

Official title: Multicenter,Randomized, Parallel,Double-blind, Comparative Study of the Superiority of the Desloratadine 0.5mg/mL and Prednisolone 4 mg/mL Versus Desloratadine 0.5mg/mL in the Treatment of Persistent Allergic Rhinitis in Children (DESPRED)

Multicenter, randomized, parallel-group, double-blind, double-dummy, comparative clinical trial of the superiority of the fixed-dose combination of desloratadine 0.5 mg/mL and prednisolone 4 mg/mL from Eurofarma Laboratórios SA versus desloratadine 0.5 mg/mL in the treatment of moderate to severe persistent allergic rhinitis in children aged 6 to 12 years.

⚠️Study will only be conducted in research centers in Brazil (please do not send e-mail if your center is outside brazil).

Read the detailed description

Desloratadine and prednisolone are active pharmaceutical ingredients (APIs) already registered in the country as monodrugs. These products are widely used and their efficacy and safety are well known in daily clinical practice in the approved indications.

Once confirmed the absence of pharmacokinetic interaction between desloratadine and prednisolone in relative bioavailability studies, this phase 3 study will be conducted with the objective of demonstrating the superiority of the new FDC containing desloratadine and prednisolone over the isolated administration of desloratadine in treatment from moderate to severe allergic rhinitis in children. The aim is to provide a new effective, safe and well-tolerated therapeutic option for dealing with these cases.

Multicenter, randomized, parallel group, double blind, double-dummy, superiority comparative clinical trial.

Children aged ≥ 6 years and < 12 years with moderate to severe persistent allergic rhinitis unresponsive to optimal treatment, including daily use of intranasal corticosteroids, will be randomized in a 1:1 ratio to receive FDC desloratadine 0.5mg/mL/prednisolone 4mg/mL - gel for oral administration by Eurofarma Laboratórios SA (experimental drug) or desloratadine 0.5mg/mL - syrup, for five (05) days.

⚠️Study will only be conducted in research centers in Brazil (please do not send e-mail if your center is outside brazil).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The total nasal symptom score (TNSS)

    Primary objective: Demonstrate the superiority of the experimental drug (FDC desloratadine 0.5 mg/mL/prednisolone 4 mg/mL from Eurofarma Laboratórios SA) compared to desloratadine 0.5 mg/mL in alleviating symptoms of moderate/severe allergic rhinitis in children through the absolute variation of the total nasal symptom score (TNSS) five (05) days after the treatment start. The TNSS is determined by the sum of the intensity scores attributed to the symptoms of nasal obstruction, runny nose, nasal itching and sneezing in the last 24 hours. Each symptom is assessed using a 4-point categorical scale (0=absent symptom, 1=mild symptom, 2=moderate symptom, 3=intense symptom).

    Measured: five (05) days after the treatment start

Secondary outcomes (1)
  1. The total nasal symptom score (TNSS) ( efficacy)

    Secondary objectives: To compare the efficacy of the experimental drug (FDC desloratadine 0.5 mg/mL/prednisolone 4 mg/mL from Eurofarma Laboratórios SA) against desloratadine 0.5 mg/mL in alleviating symptoms of moderate/severe allergic rhinitis in children through TNSS. The TNSS is determined by the sum of the intensity scores attributed to the symptoms of nasal obstruction, runny nose, nasal itching and sneezing in the last 24 hours. Each symptom is assessed using a 4-point categorical scale (0=absent symptom, 1=mild symptom, 2=moderate symptom, 3=intense symptom).

    Measured: three (03) days after the treatment start

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Desloratadine , Prednisolone and Desloratadine in people with Allergic Rhinitis, run by Eurofarma Laboratorios S.A. at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The total nasal symptom score (TNSS) (time frame: five (05) days after the treatment start). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2026.
